Write, balance and label the type of reaction:
potassium hydroxide plus phosphoric acid yields potassium phosphate and water

me understand this?

First, we need to know the chemical formula of the substances involved. It is as follows:

Potassium Hydroxide = KOH
Phosphoric acid = H3PO4
Potassium Phosphate = KH2PO4
Water = H2O

The balanced chemical reaction should be written as:

KOH + H3PO4 = KH2PO4 + H2O

Hope this answers the question.
